Monilethrix is a rare familiar disorder of unknown cause, occurring in either sex, and ueually confined to the scalp. In most cases it is manifested in early childhood. lt is characterized by localized or widespread dystrophy of hair and follicles, the shafts showing regular variations in diameter producing alternate "nodes" and "internodes" which confer a striking beaded or moniliform appearance on the hair. We experienced a case of monilethrix, which was associated with keratosis pilaris and occurred in three generations. The patient's one sibling, mother, 4 uncles and 2 aunts of mother side and grandmother with her sister were all affected with a similar diaorder of hair.

PURPOSE: To assess the efficacy of three-dimensional CT angiography (3D-CTA) using multi-detector row computed tomography (MDCT) in the evaluation of intracranial aneurysms in patients with non-traumatic acute subarachnoid hemorrhage and to describe those aneurysms which were not found 3D-CTA. MATERIALS AND METHODS: 3D-CTA was done in 40 patients with non-traumatic subarachnoid hemorrhage by using a 16-slice MDCT; conventional digital subtraction angiography (DSA) was done in 36 of those patients within 12 hours. The CT and DSA images were reviewed by two radiologists and the site, size and neck of the aneurysms were evaluated. The results from these two modalities were then compared with the operative findings. We calculated the detection rates by 3D-CTA and DSA and evaluated the size differences of aneurysms dignosed with 3D-CTA and those found at surgery. We also analyzed the locations and sizes of aneurysms missed by 3D-CTA and attempted to explain these false negatives. RESULTS: A total of 55 aneurysms were surgically confirmed in 40 patients. 48 of these were detected pre-operatively by 3D-CTA. Thus, the detection rate by 3D-CTA was 87%. The size difference of aneurysms as calculated by 3-D CTA and found operatively was as follows: less than 1 mm in 17 cases, within 1-2 mm in 15 cases, and more than 2 mm in 16 cases. Seven aneurysms were not detected by 3D-CTA. The major cause of these missed aneurysms was their small size. The undetected aneurysms were less than 2 mm in size, except for 2 instances of PCoA aneurysms. One case was not detected due to difficult image evaluation. A possible explanation of the one remaining missed aneurysm was the filling of the aneurismal sac by thrombosis. CONCLUSION: Though there were some limitations in the detection of aneurysms, 3D-CTA using 16-channel MDCT may provide sufficient pre-operative information for the management of patients with intracranial aneurysms in cases of emergency operations or DSA-failure.

The authors evaluated high resolution computed tomographic (HRCT) findings of the isolated rabbit lungs with paraquat poisoning, and the findings were correlated with pathologic specimens. The purposes of this study are 1) to obtain the HRCT findings of the normal rabbit lung, 2) to find out if pulmonary pathology can be induced in rabbits by paraquat, and 3) to correlate the HRCT findings to those of pathology. Thirty rabbits were divided into three groups: group I included four control rabbits; group II included 16 rabbits given paraquat intraperitoneally(IP group); and group III included 10 rabbits given paraquat intravenously(IV group). The rabbits were sacrificed seven, 10 and 14 days after injection of various amount of paraquat, and then the lungs were isolated for HRCT and pathologic studies. Gross and microscopic findings of the three groups of control and paraquat-injected rabbit lungs were correlated with HRCT findings. Pulmonary congestion, mild thickening of alveolar walls and septae, and multifocal micro-atelectasis were the main pathologic findings of the lungs in both groups of the rabbits. Pulmonary hemorrhage was noted in five (31%) of 16 rabbits of IP group and three (30%) of 10 IV group. Pulmonary edema was seen in one rabbit (6%) of IP and four (40%) of IV group. Typical pulmonary fibrosis was seen in one rabbit of IP (6%) and IV (10%) group, respectively. There was no correlation between the amount of paraquat and frequency of the pulmonary pathology. Pulmonary fibrosis was seen at least one week after the paraquat injection. On HRCT, pulmonary hemorrhage and edema appeared as diffuse air-space consolidation and pulmonary fibrosis as linear or band-like opacities. However, minimal changes such as mild congestion.

A case of metastatic tumor of the skin is described with literature review. Cutaneous metastases of malignant tumor is rarely seen but lung cancer in male and breast cancer in female are not infrequently reported. This patient, 37 year old male, had lung cancer, had several chest tappings for pleural effusion and a pleural biopsy. 8 months later, skin manifestation of diffuse erythematous sclerotic patches and confluent nodules was noted on pleural biopsy site, right lateral chest wall. Histopathological finding was compatible with metastatic carcinoma. This metastatic skin tumor is considered to be arisen from the lung probably due to pleural biopsy.

BACKGROUND: Irbersatan, an orally active antihypertensive agent, effectively reduce blood pressure by directly blocking angiotensin II receptors without any significant adverse effects. The purpose of this study is to evaluate the efficacy and safety of irbesartan in patients with mild to moderate hypertension. METHODS: This study enrolled 83 patients who had diastolic pressure above 95 mmHg and below 110 mmHg on two measurements. Sixty eight patients were administered 150mg of irbesartan, an angiotensin II receptor blocker, daily for four weeks as an initial dosage. If the sitting diastolic pressure was equal to or greater than 90 mmHg after a 4 week treatment period, the dosage was doubled until the end of 8 weeks. Baseline pressures, antihypertensive effect, side effects, laboratory findings were compared before and after treatment. RESULTS: Fourty two patients out of 53 patients having completed this study showed decreased blood pressure equal to or more than 5 mmHg of the sitting diastolic pressure (response rate=79%). Twenty one patients out of 53 patients showed normalized blood pressure below 90 mmHg of the sitting diastolic pressure (normalization rate=40%). The extent of decrease in diastolic and systolic blood pressure after eight week treatment was an average 11.7+/-10.1 mmHg and 16.3+/-18.9 mmHg, respectively (p<0.05). Nineteen ontoward side effects was observed in 17 patients out of 68 patients with medication (frequency of ontoward effects=25%). Only one case with headache was considered to be related to the medication. Abnormal laboratory findings were observed in eight patients, and only one case with elevation of bilirubin and ALT levels was considered to be related to the medication. CONCLUSION: In conclusion, irbesartan is a safe and effective antihypertensive drug in patients with mild to moderate hypertension with tolerable side effects.

Sebaceous carcinoma (SC) is a rare tumor, accounting for approximately 0.7% of skin cancers. SC can be classified as ocular SC (OSC) or extraocular SC (EOSC) depending on its location. Because EOSC accompanied by metastases is rare, there is a paucity of data about EOSC accompanied by metastasis. This study presents a case of an aggressive EOSC of the scalp with lymph node metastases. The patient underwent wide local excision of the primary tumor with a 1 cm safety margin and bilateral radical lymph node dissection. However, recurrence was observed 1 month after surgery. Radiation therapy and resection were performed for the recurrent tumor. However, distant metastases to both lungs eventually occurred. Here, we describe a rare recurrent case of EOSC of the scalp with distant organ metastasis with a review of the literature.

Granular cell tumor is one of the rare tumorous condition. At present there are estimated 600 reported examples of the tumor in the medical literature. Malignant granular cell tumor is a well established but extremely rare entity that is found in appr- oximately 2 % of all granular cell tumor. Diagnosis should be restricted to neoplasms that are similar in their histological appearance to benign granular cell tumors but can be seperated on the basis of cellular pleomorphism, mitotic activity, and, most importantly, their capacity to produce metastases. The authors had experienced that a 55 years old male patient had two large malignant granular cell tumors at the left thigh and left inguinal area with metastatic lesion.

Tufted angioma is a rare benign vascular neoplasm that usually occurs in children. It appears as an erythematous, purplish, indurated papule or plaque on the trunk or neck. Although it can have variable clinical manifestations, the annular or serpiginous configuration of lesions resembling tinea infections has rarely been reported. A 47-year-old woman presented with an erythematous plaque enlarging by peripheral extension to form polycyclic or serpiginous figures on her left chin and buccal cheek for 7 months without any subjective symptoms. Tinea faciale was considered as the initial clinical diagnosis, but repeated KOH tests were all negative; therefore, skin biopsy was performed. Histopathology revealed discrete circumscribed foci of capillaries scattered throughout the dermis showing a cannon ball appearance, compatible with tufted angioma. Clinical features showed considerable improvement after 2 sessions of intense pulsed light and pulsed-dye laser (5 repetitions) without any complications. Herein, we report a rare case of polycyclic variant of tufted angioma, which developed in a woman in her 5th decade.
